Description

Technical Field

[0001] This application relates to the field of road construction, and in particular to a road repair and breaking device. Background Technology

[0002] High-pressure crushing equipment plays a crucial role in road repair work. This equipment is specifically designed to crush large pieces of waste rock into appropriately sized gravel to meet the needs of road repair. The crushed road gravel can then be used as a base layer material in damaged areas of the road, thereby reducing reliance on new filler materials and minimizing resource waste.

[0003] In related technologies, Chinese utility model patent with announcement number CN214514934U discloses a high-pressure crushing device for municipal road repair. It includes a device shell, a hydraulic cylinder fixedly connected to the top of the inner wall of the device shell, a drive motor fixedly connected to the bottom of the drive shaft of the hydraulic cylinder, a crushing toothed disc fixedly connected to the bottom of the drive motor, a stone frame fixedly connected between the two sides of the inner wall of the device shell, a return spring fixedly connected to the bottom of the inner wall of the device shell, and a vibration frame fixedly connected to the top of the return spring.

[0004] The aforementioned patent employs the coordinated operation of a drive motor, a crushing disc, and a nozzle to crush waste rock while simultaneously addressing the issue of dust pollution. However, it suffers from the following technical drawbacks: due to the interaction between the crushing disc and the stone frame, it is difficult to continuously add crushed stone during the crushing process. The crushing disc must be moved above the stone frame before crushed stone can be added. When there is a large amount of road debris, the crushing efficiency will be affected. Utility Model Content

[0005] In order to improve the crushing efficiency of crushed stone, this application provides a road repair crushing device.

[0006] The road repair and breaking device provided in this application adopts the following technical solution: A road repair crushing device includes a crushing mechanism. A movable frame is fixedly connected to the lower side of the crushing mechanism. A drive mechanism for driving the crushing mechanism is installed on the upper side of the movable frame. A shield for reducing stone fragmentation is installed at the upper end of the crushing mechanism. A discharge pipe for discharging stone fragments is provided at one end of the movable frame. A control cabinet is installed at the end of the movable frame near the drive mechanism. The crushing mechanism includes a body, a movable jaw plate, and a fixed jaw plate. The body is installed on the upper side of the movable frame. The movable jaw plate is located inside the body and its upper end is connected to the drive mechanism. The fixed jaw plate is located on one side of the movable jaw plate and is connected to the body. Adjustment mechanisms for adjusting the position of the fixed jaw plate are installed at both ends of the body. The fixed jaw plate is provided with multiple locking mechanisms connected to the body.

[0007] By adopting the above technical solution, firstly, the distance between the fixed jaw plate and the movable jaw plate can be quickly adjusted through the adjustment mechanism, so as to meet the crushing needs of various road gravel; secondly, the locking mechanism can prevent the fixed jaw plate from becoming misaligned during operation, ensuring the crushing effect of the gravel; thirdly, it can effectively block the flying gravel generated during the crushing process, protecting the surrounding environment and the safety of workers, and avoiding injury to personnel from the gravel; fourthly, the movable frame facilitates the movement of the device, enabling it to crush road gravel in damaged areas, reducing the time spent transporting road gravel, and improving the crushing efficiency of road gravel.

[0008] Optionally, the adjustment mechanism includes a first push rod and a connecting block. The first push rod is fixedly connected to one side of the machine body. Both sides of the machine body are provided with sliding grooves for the connecting block to slide. One side of the connecting block is fixedly connected to the piston rod of the first push rod, and the other end is fixedly connected to the fixed jaw plate.

[0009] By adopting the above technical solution, the connecting block can be moved in the groove by controlling the extension and retraction of the first push rod, and the position of the fixed jaw plate can be precisely adjusted, thereby changing the distance between the moving jaw plate and the fixed jaw plate to adapt to the crushing needs of stones of different sizes, and better meet the crushing requirements of different road repair scenarios.

[0010] Optionally, limit grooves are provided on both sides of the machine body, and slide rods are fixedly connected between the inner walls of the limit grooves on opposite sides. A slider is slidably connected to the outer wall of the slide rod, and one side of the slider is fixedly connected to the fixed jaw plate.

[0011] By adopting the above technical solution, the setting of the limiting groove, the sliding rod and the slider can provide additional limiting and guidance for the movement of the fixed jaw plate, effectively restricting the movement direction of the fixed jaw plate, so that it can only move smoothly along the predetermined trajectory, and ensuring that the fit between the moving jaw plate and the fixed jaw plate is tighter and more accurate during the crushing process.

[0012] Optionally, the locking mechanism includes a second push rod, a locking block, and a spring. The main body of the second push rod is fixedly connected to the fixed jaw plate. One side of the locking block is fixedly connected to one end of the piston rod of the second push rod. Locking grooves for the locking block to be inserted are provided on the inner walls of opposite sides of the machine body. The spring abuts between the fixed jaw plate and the locking block and is sleeved on the outside of the second push rod.

[0013] By adopting the above technical solution, the locking block is inserted into the locking groove by the push of the second push rod, which can firmly lock the fixed jaw plate on the machine body. This can effectively prevent the fixed jaw plate from loosening or shifting due to vibration or other reasons during the crushing process, thus ensuring the normal operation of the crushing mechanism and the stability of the crushing effect.

[0014] Optionally, the fixed jaw plate has through slots on both sides near the machine body for the locking block to pass through, and the through slots are connected to the locking slots.

[0015] By adopting the above technical solution, the through slot can provide a smoother channel for the insertion and removal of the locking block, making the locking and unlocking operations simpler and faster, ensuring the fixed jaw plate is firmly locked during the crushing process, and providing convenience when its position needs to be adjusted.

[0016] Optionally, the drive mechanism includes a drive motor, a drive wheel, and a driven wheel. The drive motor is mounted on the upper side of the movable frame. An eccentric shaft that is rotatably connected to the upper end of the machine body is fixedly connected to the inner wall of the driven wheel. The middle part of the eccentric shaft is rotatably connected to the upper end of the moving jaw plate. Multiple transmission belts are rotatably sleeved between the drive wheel and the driven wheel.

[0017] By adopting the above technical solution, the driving mechanism can stably drive the moving jaw plate to move repeatedly toward the fixed jaw plate inside the machine body. When the crushed stone is placed between the moving jaw plate and the fixed jaw plate, the crushed stone can be crushed. This transmission method can efficiently transmit the power of the motor to the crushing mechanism, ensuring the stable operation of the crushing mechanism and improving the crushing efficiency.

[0018] Optionally, the shielding component includes a guide pipe and a baffle plate. The guide pipe is fixedly connected to the upper end of the machine body, and the upper end of the baffle plate is hinged to the inner wall of the feed inlet plate of the guide pipe. A nozzle connected to a water pipe is installed on the upper side of the guide pipe.

[0019] By adopting the above technical solution, the baffle plate can effectively shield the crushed stone generated during the crushing process, preventing the crushed stone from splashing out of the feed inlet without affecting the input of crushed stone, ensuring the continuity and stability of the crushing process. After connecting the nozzle to the water pipe, the generation of dust can be effectively reduced, the pollution to the environment can be reduced, and the overall working efficiency of the device can be improved.

[0020] Optionally, the lower side of the movable frame is provided with a positioning part for inserting the discharge pipe.

[0021] By adopting the above technical solution, the crushed stone can be smoothly discharged from the device through the discharge pipe after crushing, preventing the crushed stone from accumulating inside the device. In addition, the positioning part can provide an accurate installation position for the discharge pipe, making the installation of the discharge pipe more convenient and quick.

[0022] In summary, this application has the following beneficial effects: 1. This application enables continuous feeding and crushing of crushed stone, and the distance between the fixed jaw plate and the moving jaw plate can be quickly adjusted through the adjustment mechanism, which can meet the crushing needs of road crushed stone of different sizes, and facilitates the movement of the device, reducing the time consumed in transporting crushed stone, thereby improving the crushing efficiency of road crushed stone.

[0023] 2. This application can effectively block the flying debris generated during the crushing process through the shielding component, reduce the generation of dust, protect the surrounding environment and the safety of workers, and prevent the debris from causing injury to personnel.
